Description
Technical field
The present invention is relevant for combining structure and the method thereof of a kind of fan insulating frame and beam barrel, espespecially a kind of combining structure and method thereof of utilizing laser fusing fan insulating frame and beam barrel that has reinforced insulation frame and beam barrel structural strength and reach cost-effective effect.
Background technique
Much equipment, such as fan etc., all can reach by the driving of motor the effect of running, so the quality quality of motor can be decided by the quality of relevant device now.Wherein, bearing affects the critical elements of motor operation especially, if bearing cannot provide rotating shaft lubricated and fixing effect, gently produces noise, heavy can cause shortening of motor working life.
Because the bearing of known fan is in order to access sufficient lubrication effect, middle pipe and the oil-impregnated bearing that in use, conventionally can make with metallic material (as copper) are used in combination, wherein in this kind of metal pipe because adopting turning processing, therefore machining accuracy is higher, so except oil-impregnated bearing is press-fitted and can easily accomplishes suitably to coordinate while being positioned in this metal in pipe, the copper ring arranging on oil-impregnated bearing in metal in pipe is close-fitting elasticity more easy to control also, and suppress relative oil-impregnated bearing by copper ring, get loose out when avoiding oil-impregnated bearing to relatively rotate with the axle center of fan, to stablize fan running.
Though between pipe and copper ring and oil-impregnated bearing, quality of fit is more easy to control in metal, but in this metal tubular construction comparatively complexity and procedure numerous and diverse, as needing extra turning to process class's step, pipe inside in this metal places for oil-impregnated bearing, or bore and oil-impregnated bearing external diameter gap when excessive in metal, need extra turning processing to expand bore in this metal and can be permitted in scope to the deviation that is applicable to oil-impregnated bearing external diameter, therefore make to cause integral production cost to improve.
Another person, another structure of known fan pipe and oil-impregnated bearing in plastic rubber ejaculate molding are used in combination, and the copper ring arranging on the oil-impregnated bearing in Yu Zhongguan, to suppress by this copper ring when relative oil-impregnated bearing avoids oil-impregnated bearing to relatively rotate with the axle center of fan, get loose out, to stablize fan running; Though this another structure of known fan is utilized plastic rubber ejaculate molding to go out middle pipe and manage escapable cost in the metal of above-mentioned known fan structure, but extend another problem, when when manufacturing, Unitary injection formed is managed in this exactly, easily cause the tolerance of bore in it larger, and then the copper ring elasticity that causes being positioned on the oil-impregnated bearing in middle pipe is difficult to control, when if the middle mouth of pipe footpath of ejection formation is excessive, can make described copper ring cause and cannot effectively suppress oil-impregnated bearing in middle pipe Nei Taisong, so that oil-impregnated bearing is easily deviate from; If when the middle mouth of pipe footpath of ejection formation is too small, easily causes on oil-impregnated bearing and middle tubular construction and damage, as middle tracheal rupture, oil-impregnated bearing distortion or oil-impregnated bearing shrinkage cavity etc.
So no matter the middle pipe of known fan is with metal turning processing or plastic cement Unitary injection formed, bearing is in the inner all to suppress bearing by copper ring, the effect of rotating to stablize fan, because current electronic product (as notebook computer) designs towards slimming direction gradually, make the radiation fan in electronic product certainly will also must be along with slimming develops, so dealer just develops a kind of microminiature fan.
And the middle pipe of known microminiature fan be in metal pipe or plastic cement in manage, in it, equally also must be installed with oil-impregnated bearing, but copper ring really cannot be set on the oil-impregnated bearing in Yu Zhongguan and suppress oil-impregnated bearing, because copper ring cannot produce the middle pipe caliber size that meets microminiature fan, so be not all equiped with copper ring in the middle pipe of at present general microminiature fan, make microminiature fan when rotating, easily cause oil-impregnated bearing slide and produce different sound and reduction of service life, and then also can affect the problem of fan rotational efficienty.
Therefore, how to solve above-mentioned public problem and disappearance, the inventor who is this case desires most ardently to the relevant manufacturer that is engaged in the industry the direction place that research improves.
